"Do you know this locket now, Sordello? Truly know it?"
"Yes, Maestro."
"Could you mistake it for another?"
"No, Maestro."
"Good. Now I command you. When you see this locket again, it will be a sign. It will mean that you are to kill Simon de Gobignon at once. As soon as you see the locket, you will take up the first weapon that comes to hand, and you will await your first good chance, and you will strike him down. Do you understand?"
"Yes, Maestro."
"Will you do it?"
"Yes, Maestro. With much joy."
"Say what you will do, Sordello."
